A car with mass $1500\,\text{kg}$ moves downhill at a steady speed of $30\,\text{m s}^{-1}$. The slope makes an angle of $6.0^{\circ}$ with the horizontal, as illustrated. The size of the total resistive force on the car is $2000\,\text{N}$. Determine the power output of the car’s engine.
- A$14\,\text{kW}$
- B$60\,\text{kW}$
- C$110\,\text{kW}$
- D$380\,\text{kW}$
